MOLD.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed January 20, 1.906. Serial No. 241,979.

To all whom, it may concern:

Be it known that I, DANIEL G. ZEIGLER, a citizen of the United States,residing at Sumter, in the county of Sumter and State of South Carolina,have invented certain new and useful Improvements in Molds, of which thefollowing is a specification.

The object of this invention is to provide an improved construction ofmold especially designed for molding brick, tile, buildingblocks, or thelike in connection with a support upon which the mold parts arepeculiarly mounted in order to admit of interchanging and adjustment ofsuch parts for making the brick or blocks of different sizes and shapes.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result, reference is to be had to the followingdescription and accompanying drawings.

\Vhile the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still some of the preferredembodiments of the invention are shown in the accompanying drawings, inwhich- Figure 1 is a plan view of a device embodying the essentialfeatures of the invention. Fig. 2 is a longitudinal vertical sectionalview on the line X X of Fig. 1. Fig. 3 is a transverse sectional view onthe line Y Y of Fig. 1. Figs. 4, 5, and 6 are horizontal sectionalviews, parts broken away, of

- molds and core-pieces therefor, the molds being of different generalconstruction for making different shapes of tiles or blocks. Fig.

7 is a side elevation of a core-block, such as is preferably used inconnection with the invention.

Corresponding and like parts are referred to in the'followingdescription and indicated in all the views of the drawings by the samereference characters.

Specifically describing the detail parts of the device which comprisesthis invention, 1 denotes the support, which is comprised, es-

sentially, of a frame 2 of approximately rec- 1 toward thelowerextremities thereof, as shown 100 tangular form, having sides and ends.The sides of the frame are connected by means of transverse cleats orcurved pieces 3, which are of any suitable number sufficing to give thenecessary rigidity to the frame. The mold proper is mounted upon thesupport 1, and for this purpose spaced longitudinal bars 4 are provided,and transverse spaced bars 5 are also used. The bars 4 and 5 aresuperposed mounted upon the frame 1, the sides and ends of the framebeing provided with strips 6 and 7, respectively, the upper sides ofwhich strips are provided with longitudinal recesses 8 at suitableintervals. 5 are preferably reduced, as shown at 9, so that said endsmay be readilyseated in the recesses or notches 8 of the strip 6 inorder to positively position the said bars in an adjusted position uponthe frame 1. In their disposition upon the frame 1 the bars 4 and 5 maybe adjusted toward and from each other, as desired, admitting ofadjustment of said mold parts. The mold is of sectional construction andconsists of the sides 10 and the ends 11, both the sides and ends beingprovided at their lower portions with engaging members 12, preferably oflooped formation, which members 12 are adapted to receive the bars 4 and5 in order to secure the mold parts thereto. The members 12 removablyattach the sides and ends of the mold to the bars 4 and 5, so that theseparts may be readily displaced in order to admit of use of larger orsmaller mold-section in making tile or blocks of different sizes andshapes. The members 12, further, so attach the sides and ends of themold to the bars 4 and 5 that these sides and ends may be readily throwndownwardly in order to rest flat after the mold has been used and topermit of drying of the molded article in the customary manner. Suitablecore-blocks 13 are used in connection with the mold, and said blocks maybe provided at their upper ends with handles 14, the lower extremitiesof the blocks having pins 15 projected therefrom to enter openings inthe bottom of the mold, so as to properly center the core-blocks whenthe latter are in operative position. The sides of the core-blocksconverge slightly The ends of the bars 4 and most clearly in Fig. 7 ofthe drawings, to facilitate displacement of the cores after the moldingoperation.

It will be noted from the foregoing that should it be desired to moldtiles or blocks of greater or less width the longitudinal bars 1 may bereadily adjusted by a separating or reverse movement thereof relative toeach other, and in the same manner the length of the article to bemolded may be also varied. Of course it will be obvious that differentsizes of sides 10 and ends 11 for the mold may be utilized in connectionwith the bars 1 and 5, said parts of the mold being removably attachedto the bars in a manner before set forth. The recesses or notches 8 inthe end strips 7 of the frame 1 are of less depth than those in the sidestrips 6 in order that the transverse bars 5 may rest in a planesomewhat below the plane in which the longitudinal bars 4 are located.The articles molded in the use of the invention may thus be made of anywidth, length, or depth, and when the molding operation is completed thesides and ends of the mold may be thrown downwardly in order to exposethe article for drying purposes. The parts of the mold are held in placeby means of rigid bars 16, attached to the sides 10 of the moldlongitudinally thereof, the ends of the bars 16 projecting beyond theends 11 of said mold. The projecting ends of the bars 16 are notched onopposite sides, as shown at 17, and the ends 11 of the mold are providedwith pivotal clamp-bars 18, the ends of which are notched, as shown at19, the notches being in opposite sides. By pivotal movement of theclampbars 18 of the ends 11 of the mold the notched portions 19 thereofwill engage in the notched portions 17 of the bars 16 of the sides 10,thereby firmly holding the several sections of the mold in place. Themembers 18, of course, by pivotal movement may be engaged or disengagedfrom the member 16 in assembling or disassembling the parts.

Fig. 1 of the drawings illustrates the use of a partition or divisionplate 20, arranged longitudinally of the mold between the side 10thereof. The use of the plate 20 will admit of making two entire blocksor tiles in the same molding operation, as will be obvious.

In Fig. 4 an annular partition 21 is used in connection with threecore-blocks 13. The tile or block molded in the device shown in Fig. 1would be especially adapted for use at corners of wall construction.

Fig. 5 illustrates a further modification of the idea shown in Fig. 4,the block which will be molded in the construction of this figure beingalso of annular formation, because of the use of the partition 22 andadjacent partitions 23, 24, and 25. hen it is desired to construct atile or block of curved forma tion, the mold is provided with curvedfront and rear plates 26 and 27, respectively, and end plates 28, aconstruction fully shown in Fig. 6 of the drawings.

The invention involves a comparatively simple device which may bemanufactured in such a manner as to be susceptible of a very broadapplication in molding blocks, tiles, or the like.
